How can we save the world?

We can save the world, we can help the world to be a better place.
We have to do something. The World is the most wonderful place that someone has given to us and it is our house, our home. We have to work to do that and we have to help each other, this is the most important thing that we can do, but everyone has to do that. Two weeks ago we watched this video Home, and we spoke about what we can do to help the world, how can we help it?
We can help the environment in many ways. But we can help men to be better too.
I watched a film some years ago, I liked it a lot, and I suggest to watch it Pay it forward- change lives.
We watched Vegan&Vegan too.
I think that everyone can change the world, everyone with his choises make life different. We have so many resources that we can think that they will never finish. They will finish soon, if we don't try to save our resources.
We must not buy a lot of things that we will throw away because we don't really need them. It's stupid but everyone of us do that. We don't walk, we usually go by car everwhere! We let turned on the light in our houses, we let computer tourned on all the day, everyday... and someone everynight. It's not the best for us. Energy costs, energy must be paid, and we pay it, it isn't infinite. Our resources cost and we have to learn to use them in the best way we can.
I hope it will happen soon, because everyone needs a happy place where can live happy, and if we destroy the world nothing will be as wonderful as it is now.

We need it. We have to respect it. We have to learn going out on foot, we have to learn not spending many hours on the net or watching tv. We haven't to spend energy uselessly, we need energy.
